How many movements does a typical string quartet usually have?

A typical string quartet usually consists of four movements. This structure is commonly based on classical compositions, particularly those from the Classical period, such as string quartets by composers like Haydn, Mozart, and Beethoven. The four-movement form often follows a specific pattern: the first movement is typically in sonata form, the second movement is usually slower and lyrical, the third movement is often a dance-like minuet or scherzo, and the fourth movement serves as a lively finale, which might be in rondo form or sonata form again. This quartet format allows for a rich exploration of musical themes and variation, contrasting moods, and intricate interplay between the performers, which is a hallmark of chamber music composition. While some quartets may deviate from this traditional structure, the four-movement format remains the standard in most classical string quartet works.
